Abstract

UMKM Nyusu Enak merupakan usaha susu yang berdiri dari tahun 2022. Persoalan yang dihadapai oleh UMKM Nyusu Enak adalah tidak tepatnya pengendalian kebutuhan bahan baku, belum mampu menetapkan total minum pemesanan kembali yang memicu pembelian baru, kekurangan persediaan jumlah bahan baku yang akan digunakan selama proses produksi. Penelitian ini menggunakan metode deskriptif kualitatif adalah teknik penulisan yang memaparkan kejadian sesungguhnya mengenai objek penelitian, sesuai dengan keadaan sesungguhnya saat penelitian dilakukan. metode ini menghitung jumlah optimum dari persediaan bahan baku utama susu dengan menerapkan model Kuantitas Pemesanan Ekonomis dan Waktu Pemesanan Kembali yang hasil data penelitiannya akan disuguhkan berupa angka dan dijelaskan dalam kalimat kualitatif. Dari hasil penelitian diperoleh total kualitas order sebesar Rp., 772.368.411 dan didapatkan safety stock sebesar 56,19 kg.

Abstract

Anxiety is a common mental health issue among adolescents, particularly in Indonesia, where socio-cultural factors contribute to the challenges they face. Mindfulness-based interventions (MBIs) have been shown to alleviate symptoms of anxiety across various populations. This study investigates the effectiveness of MBIs in reducing anxiety symptoms among adolescents in Indonesia. The primary aim is to assess how these programs can help adolescents manage anxiety and improve their overall well-being. A mixed-methods approach was used, involving both qualitative interviews and quantitative surveys with 150 adolescents who participated in a 6-week MBI program. Pre- and post-program anxiety levels were measured using standardized tools such as the State-Trait Anxiety Inventory (STAI). The results revealed a significant reduction in anxiety symptoms among participants, indicating the potential of MBIs in promoting mental health in adolescents. The findings suggest that incorporating mindfulness practices in educational settings could be an effective approach to addressing adolescent anxiety in Indonesia. The study concludes that MBIs are a viable and beneficial intervention for reducing anxiety symptoms in adolescents, with broader implications for school-based mental health programs.

Abstract

The elderly’s Posyandu is one of the government programs in overcoming health and social welfare problems for the elderly. Based on the results of a preliminary study at the UPTD Puskesmas Kuningan, West Java, it was found that the coverage of elderly’s posyandu visits had only get 36.14%. That score is still very far from the Indonesian National Standard that 80%. The purpose of this study was to identify whether there was a significant relationship between the use of posyandu visits by the elderly and the health status of the elderly in the working area of UPTD Puskesmas Kuningan. This study used a cross-sectional research design with an analytical observational approach. 93 elderly being respondents in this study were taken using the proportional stratified random sampling method. Data collection was done by using a questionnaire. Data were processed and analyzed using SPSS version 16 for windows with chi-square statistical test. The results obtained are P-value = 0.000 (< = 0.05). That means, there is a significant relationship between the use of posyandu by the elderly and their health status. The results of this study are expected to be a source of information for health workers to play an active role in increasing the interest and motivation of the elderly to take advantage of the posyandu services for the elderly in order to improve their health status.

Abstract

Menghabiskan waktu bersama orang lain sangat penting untuk kesejahteraan emosional dan mental lansia. Hubungan keluarga dan fungsional kognitif diketahui merupakan faktor penting yang dapat mendukung interaksi sosial di kalangan lansia. Namun, bagaimana dampak hubungan dukungan keluarga dan fungsi kognitif terhadap kemapuan lansia dalam  berinteraksi sosial masih belum diketahui dengan jelas. Oleh karenanya, penelitian ini bertujuan untuk menganalisis hubungan antara dukungan keluarga dan fungsi kognitif terhadap kempuan interaksi sosial lansia. Penelitian ini menggunakan metode cross-sectional dengan besar sampel sebanyak 59 orang berusia rata-rata 60 tahun yang terdaftar sebagai penduduk Desa Jadimulya Kecamatan Gunung Jati Cirebon yang diambil dengan tehnik stratified random sampling. Data dikumpulkan dengan menggunakan kuesioner dan dianalisis dengan uji korelasi Rank Spearman Test. Adapun hasil penelitian ini menunjukan (1) ada hubungan antara dukungan sosial keluarga terhadap kemampuan interaksi sosial pada lansia  dengan nilai p-value = 0,000 < 0,05 dan  rh0 = 0,547; (2) ada hubungan antara fungsi kognitif terhadap kemampuan interaksi sosial pada lansia dengan nilai p-value = 0,000 < 0,05 dan  rh0 = 0,478.

Abstract

Cholesterol oxidase (CO) was successfully produced from Streptomyces sp. via the submerged fermentation method, and 69 U/mL enzyme activity was obtained. This study aimed to determine cholesterol oxidation kinetics and the production of CO as a catalyst. The enzyme was diluted to 0.15, 0.075, and 0.00375 U/mL for the oxidation reaction. The substrate was also prepared in three concentrations: 3.23, 6.46, and 12.93 mM. The optimization of conditions for enzymatic cholesterol oxidation was investigated through measurement of the effect of initial cholesterol and enzyme concentrations. Cholesterol concentration was rapidly measured via high-performance liquid chromatography (HPLC). The kinetics of CO were modeled using the first-order irreversible reaction. An enzymatic kinetic model was derived, and it was verified using experimental data and sensitivity analysis. Based on the experiment, the highest enzyme concentrations of crude and commercial CO can oxidize the substrate up to 84% within 240 min. However, the oxidation reaction showed a slightly different behavior in the early 60 min, and crude CO exhibited a slower substrate oxidation. The kinetic rate constant obtained by Euler’s method reached 1.0 x 10−3/min and 1.41 x 10−3/min for 0.15 U/mL crude and commercial CO, respectively.
